ABSTRACT:
A method for synthesizing hydrocarbons from a methane source which comprises contacting methane with an oxide of Pr having combined therewith an amount of alkali and/or alkaline earth metal which is sufficient to improve the selectivity to higher hydrocarbon products. The oxide is reduced by the contact which is carried at about 500.degree. to 1000.degree. C. Reducible oxides of Pr are regenerated by oxidizing the reduced composition with oxygen. The oxide Pr.sub.6 O.sub.11 is particularly effective in the process.
